Allowable expenses for Buy To Let rental property while it is being upgraded for renting again

I have a buy to let flat that I have rented out for several years that needed updating and improving. The property was off the market for a several months between starting the restoration, finishing it and welcoming the new tenant. Am I able to claim expenses for the financing cost (interest only I know), service charge, council tax and standing charges during the down period? Thanks so much for your help.

Hi Bertram,
As there was still the intention to rent the property out, but the maintenance and repairs, prevented this, you can claim those costs, such as service charges, council tax etc.
